The exam below is simply a sample test, portions of which were given to students in 1995. This
sample exam is not meant to be all inclusive. Rather, it should be used only to give you an idea of
how I design many of my exams. Be sure that not all information in the course is contained within
the body of this sample exam.
ANIMAL PARASITOLOGY 625
SAMPLE EXAM #1 (100 points) MONOGENES, DIGENES, CESTODES
NOTE: A species is binomial
- For each of the following terms, give a one sentence or less definition AND give a parasite
species for which the term applies (2 points each, 20 points total).
- Gynocophoral canal
- For each of the terms below, write in an appropriate species of trematode or cestode behind
that term (2 points each, 22 points total).
- Slime balls
- Hydatid cyst
- Salmon poisoning
- Yellow grub disease
- Parasitic castration
- For each type of trematode listed below, give a species (2 points each, 10 points total).
- For each type of larval stage listed below, give a species (2 points each, 10 points total).
- Multilocular hydatid cyst
- About 60 miles south of the Arizona border, on the Gulf of California, is a small Mexican
village (not on the map) called Cholla Bay. It is composed, in part, of Americans who, for one
reason or another, have chosen to exit the US and remain obscure. There is a bar there called
J.J.'s, and you can sit for hours on the patio overlooking a large estuary imbibing pitchers of
Margaritas. Within the estuary are millions of snails, and resident populations of invertebrates,
birds, fish, etc. You crack open some of the snails and find numerous sporocysts, and also rediae
that are producing numerous furcocercous cercariae. Based on your knowledge of trematode life
cycles, propose a HYPOTHETICAL (but very logical) life cycle for this trematode (10 points).
- Within the cestodes are multiple, distinct types of attachment organs
on the scolex. List four distinct types and tell how you can distinguish
each from the others (2 point each, 8 points total).
- Diagram the complete life cycle of Dicrocoelium dendriticum. Label all stages (10
- Diagram, compare, and contrast the life cycles of typical terrestrial versus aquatic cestode life cycles (10 points).
